Specification of Letters Patent.

ers, of which the following is a specification.

The present invention relates to improvements in hydrocarbon burners of the retort type, and is designed to simplify the construction of burners of this character, and at the same time increase the efliciency and durability of these devices.

The burner is adapted for use in connection with a stove or furnace, and is intended to be located in the fire chamber of-the stove, for heating purposes.

The invent-ion consists in certain novel features of construction and combinations and arrangements of parts as will be hereinafter pointed out, and more clearly set forth in the claims.

In the accompanying drawings I have illustrated one example of the physical embodiment of my invention constructed according to the best mode I have so far devised for the practical application of the principles of the invention.

Figure 1 is a vertical central sectional view of a hydrocarbon burner, embodying the novel features of my invention. Fig. 2 is a horizontal sectional View on line 2, 2, looking down. Fig. 3 is a horizontal sectional view on line 3-3 looking up. Fig. 4 is a detail view of a modified form of oil supply pipe arrangement. a

In the preferred embodiment of my invention, the burner is inclosed within a retort which comprises the two sections 1 and 2 forming a spherical chamber, with the upper or dome section of the retort overlapping the lower section as at 3, and forming a closed joint. The fuel inlet pipe 4 is illustrated as entering centrally of the dome section 1, and the end 5 of the pipe is open inside the retort. At its lower end the retort is closed by the dished bottom 6 which is provided with edge or peripheral flange 7 to receive the open lower end of the retort section 2.

The retort is supported from the base plate 8 by means of post-s (three being here illustrated) as 9 which .are integral with the base plate, and project into complementary sockets 10 in the under side of the retortbottom plate. In this manner the burner may be supported in the stove or furnace from the base plate. An open threaded boss 11 is formed centrally of the base plate 8, and into this boss is screwed the lower section 12 of an air inlet pipe, the upper section 13 of the pipe being seated in the upper end of the lower section as shown. The bottom-plate 6 is perforated at 14 to accommodate the air pipe, and it will be seen in Fig. 1 that sufficient space is provided at the perforation 14 for the passage of gases.

A conical cap 15 is located within the retort just below the open end 5 of the inlet pipe. This cap is supported upon cleats 16. At its perimeter the cap is fluted as at 19 and its conical face is formed wit-h flutes 0r corrugations 20 which form channels extending from the apex of the cap to its fluted perimeter.

Suspended from the air pipe 13 by lugs 17 is a tapered vessel 22 which surrounds the air tube 13 and a portion of the lower section 12, and this tapered vessel or tube, which, at its upper end, is slightly less in diameter than the greatest diameter of the cap 15, tapers in diameter so that a restricted space 23 is formed between the end of the tube and the air pipe. The tube 22 is formed with a series of circumferential shoulders or offsets 24.

The mode of operating the burner is as follows: The complete device as shown, is inclosed within the fire chamber of'a stove or furnace and fuel oil is fed through pipe 4. When the oil reaches the fluted openings at the edge of the burner cap, the fuel in the crude oil is burned and gases formed in the retort. The gases pass downward to the opening 14, and the air, which is flowing up through the air pipe and down between said pipe and the vessel 22, mixes with these gases, the result being that the gases at their cumulation of products of combustion of the oil, but allows the products to drip from the offsets and finally run off from the dished bottom of the retort, through, the opening 14 and onto the base plate 8. A natural draft for air through the air pipe is provided as shown by the arrows, and the gases; are thoroughly eommingled at the point of ignition or perforation 14.

In Fig. 4 I have illustrated a modified structure wherein theoi l pipe 4 entersu pe arldly through the. air pipes and pierces through theapex of the cone15, so that the infiowing oil may spread over, thecap 15, as iIithQfQIIlfl shown in Fig. 1,

' What 1 claim is 1. The combination in a hydrocarbon burner With an inclosing retort having a centrally perforatedibottom and a fuelpipe opening into the retort, of an air pipe extendinginto the retort, a'tube encircling said air pipe, and a burner cap extending over the open ends. of said air pipeand tube and located; between said members and, the inlet fuel-pipe. i

2. The combination in a hydrocarbon burner With an inclosing retort having a perforated bottom and a fuel pipe, of an air p'ipe extending into the retort, a tapering tube formed With annular offsets and en- 'oircling said air pipe, and a burner cap exand tube.

3. The combination in a, hydrocarbon burner With an inclosing retort having a perforated, bottom'and, inlet pipe for fuel, of an air pipe, a tapering tube inelosingsaid air pipe, anda conical burner oap haying a fluted edge extendingbeyond the open ends f a nbeand pipe-l In testim ny whereof I afiix, inysignature n presen f; wq n ses,
